AFNetworking 2.0 当Deployment Target 低于6.0时,AFURLConnectionOperation.h,AFURLSessionManager.h
@property (nonatomic, strong) dispatch_queue_t completionQueue;
由于sdk低于6.0时,dispatch_queue_t ARC没有托管,出现提示错误
Property with 'retain (or strong)' attribute must be of object type
修改为
#if OS_OBJECT_USE_OBJC @property (nonatomic, strong) dispatch_queue_t completionQueue; #else @property (nonatomic, assign) dispatch_queue_t completionQueue; #endif
本文介绍如何解决AFNetworking2.0在DeploymentTarget低于6.0时遇到的dispatch_queue_t属性错误问题,通过条件编译实现不同版本SDK间的兼容。
